Abstract (en)
[origin: WO9107587A1] A water current energy converter designed for and capable of converting the flow energy of a moving body of water into electric power comprises at least one water driven flow machine, especially a water driven turbine, an electric power generator (19) and a hydraulic energy transfer system arranged between the water turbine(s) and the power generator (19). According to the invention in at least one thoroughfare flow duct (8) of a floating buoyant body (2) at least one pumping unit (10) comprising a hydraulic rotary pump (11, 12) coupled to a shaft of the water driven turbine is provided. The buoyant body (2) is held by anchoring means (1) in predetermined orientation and in substantially stationary position in a surface water. The hydraulic rotary pumps (11, 12) form component parts and serve hydraulic pressure sources in the hydraulic energy transfer system.
